GPT-5.4 vs Grok 4 for Math

Winner: GPT-5.4. The MATH Level 5 external benchmark score is not available for either model in the payload, so our decision is based on internal and supplementary external data. In our testing GPT-5.4 outperforms Grok 4 on the task-critical metrics for Math: structured output (5/5 vs 4/5), creative problem solving (4/5 vs 3/5), and agentic planning (5/5 vs 3/5). GPT-5.4 also has higher safety calibration (5/5 vs 2/5). Grok 4 does beat GPT-5.4 on classification (4/5 vs 3/5) and ties on strategic analysis and faithfulness, but those do not overcome GPT-5.4's advantages in format fidelity and stepwise reasoning. Supplementary external scores available in the payload further support GPT-5.4: it scores 76.9% on SWE-bench Verified and 95.3% on AIME 2025 (Epoch AI). Grok 4 has no SWE-bench/AIME entries in the payload. Therefore, for math problem solving and rigorous formatted solutions, GPT-5.4 is the definitive pick.

Task Analysis

What Math demands: precise multi-step reasoning, error-free symbolic manipulation, adherence to output formats (LaTeX/JSON), reliable numerical strategy and tradeoff reasoning, access to long context for extended derivations, and correct tool selection when calling calculators or symbolic engines. The payload includes a primary external benchmark entry (MATH Level 5) but both models lack scores for it in the data, so we cannot use it to decide. We therefore treat external SWE-bench Verified and AIME 2025 scores (when present) as supplementary domain evidence — these are attributed to Epoch AI. Internally, the most relevant test signals for Math are strategic analysis (nuanced numeric tradeoffs) and structured output (schema/format fidelity). In our testing GPT-5.4 scores 5/5 on both strategic analysis and structured output (the latter vs Grok 4's 4/5), indicating stronger end-to-end stepwise solutions and format compliance. Other supporting metrics: tool calling (4/5 both) matters for calculator/symbolic tool workflows and is tied; long context (5/5 both) supports long derivations equally; faithfulness (5/5 both) reduces hallucination risk. Where available, external results bolster the picture: GPT-5.4 scores 76.9% on SWE-bench Verified and 95.3% on AIME 2025 (Epoch AI), signals that map to coding/math and competition math strength respectively. Because the canonical MATH Level 5 score is missing for both models, our verdict relies on these internal and supplementary external indicators.

Practical Examples

  1. Competitive olympiad-style problems (AIME/advanced contest): GPT-5.4 is stronger — it registers 95.3% on AIME 2025 (Epoch AI) in the payload and scores 5/5 on strategic analysis in our tests, so expect better tradeoff reasoning and solution strategies. 2) Structured solutions for publishing or automated grading: GPT-5.4 scores 5/5 on structured output vs Grok 4's 4/5 in our tests, so GPT-5.4 will more reliably produce correct LaTeX, JSON answer schemas, or step-tagged proofs. 3) Long derivations or multi-part problem sets: both models tie at 5/5 for long context and 4/5 for tool calling, so either handles long contexts and tool workflows; choose GPT-5.4 when you also need stricter format fidelity. 4) Problem classification and routing: Grok 4 wins classification 4/5 vs GPT-5.4's 3/5 in our tests — use Grok 4 to triage problem types (algebra vs geometry vs combinatorics) before dispatching to a solver. 5) Code-based math or verified coding fixes: GPT-5.4 has a supplementary 76.9% on SWE-bench Verified (Epoch AI) in the payload, suggesting stronger performance on real GitHub issue resolution that involves math and code; Grok 4 has no SWE-bench entry in the data. 6) Safety-sensitive or instruction-restricted math (e.g., constrained content): GPT-5.4 scores 5/5 on safety calibration vs Grok 4's 2/5, reducing risk of unsafe or disallowed outputs in constrained settings.

Bottom Line

For Math, choose GPT-5.4 if you need rigorous step-by-step solutions, high format fidelity (LaTeX/JSON), competition-level problem solving, or safer, more conservative outputs — GPT-5.4 scores 5/5 vs Grok 4's 4/5 on structured output and holds higher creative problem solving and safety scores in our tests. Choose Grok 4 if your primary need is fast problem classification and routing (classification 4/5 vs GPT-5.4's 3/5) or if you prefer a model that ties on strategic analysis and long context while you rely on external pipelines for final solution formatting.

How We Test

We test every model against our 12-benchmark suite covering tool calling, agentic planning, creative problem solving, safety calibration, and more. Each test is scored 1–5 by an LLM judge. Read our full methodology.

For math tasks, we supplement our benchmark suite with MATH/AIME scores from Epoch AI, an independent research organization.
